A further object of this invention is to provide ineens for ministeri-inf* Water from Water dome to n cooking vessel of e do` inestic steamer.

.My invention consists in the construction, arrangement und cmnbino-tion o elements hereinafter set forth, pointed out in my claims Lind illustrated by the ziceoinponying drawing, in Which-` Figure 1 is un elevation, Partly in section,`

of my improved device. Fig. 2 is :t plan of the sume, the cover beingn removed. Fig. 3 is horizontal section on the indicated line of Fig. 1. Fig. l is e horizonte); section on the indicated line fi-l of liff'. 1, showing s modified forni of :i part or the device. Fig. 5 is a cross-section on the indicated line 5-5 of Fig. 4. Fi s. 2,3, i and 5 nre on n smaller scale thsnlsig. 1.

lin the construction of the device es shown.

the numeral 10 design-etes s cooking vessel or boiler, preferably made of sheet instel with s flut bottoni, en annular flaring Wall und :in open top. vThe vessel 10 preferably is provided with dizinietri :uliy arranged outwardly projecting handles 11, W iich handles preferably are inode of sheet. metal and rigid reist-ive 'to 'the well of the vessel.. The vessel 1U preferably is provided with n wulcr glass or gege 12 disposed yvertically outside 'of und ,communicnling ut'nifts' ends through the u'ull ot' the vessel. The water gloss or gage 1 2 has the usual function of indicating' the depth of Water in the cookingvessel or boiler 10. l gutter 13 is mounted on, surrounds und is urrunffed concentric ywith thcf upper marginal portion of the will of the vessel 1G. The gutter 13 preferably is mede or sheet metal und is sealed to the outer surface rof the wall of the vessel l0. The gutter 13 has its upper margin :it greater altitude than the upper margin of the vessel l() in order that any overflow from seid `futter muy dischnrgc within seid vessel instt-ud ot' over the rim of the gutter. A. trivet 1l is mounted in und rests on the bottom of the vessel 1Gv l'n one form the trivet 14 consists of un inverted sheet metal piurhuving n perforated bottom; and in another forni seid trivet consists of :in annular metal ring V15, src-shepcd metal radial wires 17 extending through said ring und sections (Figs. 4i and 5).

In the construction es shown in and 5 the src-shaped sheetmetal sections 16 muy be adjusted rlidially relative to the rin 15, along the Wires 17, to expend or contract the supporting surface or the trivet. Culinary vessels 1S, 19, 2O are shown within the vessel 10 and supported by the trivet 14. These vessels 18, 19, 20 are shown es triengulur in plan' view :ind udepted to nestle eompectly in the seme horizontal plone. it is to be understood, however, that these vessels 18, 19 2O may be substituted by any other vessel orivelssels of suitable shape when desired and also may be provided with removable covers. The Vessels 18, 19, 20 are dented to contain food to be cooked and not only serve to contain said food-but also hold it out o'eooking water contained in the vessel 10. l also have illustrated s common skillet 21 Within the vessel 10 and supported on the nestled vessels 18, 19, 20. The, handle of the skillet 21 extends radially across the upper margin of the Wall of the vessel 10. A lid or cover is provided for the vessel 10 -and preferably is constructed as a Water dome in the following manner: Supe osed spherical segments 22, 23, mede on di erent orcs, are arranged onewithin the other so that they bear concentric relations, und are -connected their nnirgins by a list ring 24C.

The marginal portions of the spherical segsections 16 und.

rig-S. i

lois` lll) .The marginal ments 22, 28 are sealed to inner and outer 24.. ortion of the spherica segment 22 exten s within and concentric with the upper margin of the wall of the-vessel l() and the marginal portion of the spherical segment 23 extends Within the gutter 13 and restsjon the ,bottom thereof. lhc marginal portion of the spherical segment 223 is concentric with and outside of and spaced from the upper marginal portion of the wall of the vessel 10.A Registering notches 25, 26 are formed inthe marginal portions of the spherical segments 22, 23 beneath the flat ring 24 and provide space for the handle of the skillet 21. A vent tine 27 is mounted on and communicates with an aperture at the apex of the segment 22 and has its open upper end ortion in close proximity to thc inner sur ace of the apex of the segment 28. A valve chamber 28 is mounted through and connects the segments 22, 23 and communirates with the interior of the water dome bemargins respectively of the tlat rin tween said segments. A needle valve 29 is mounted inthe valve chamber 28 and controls the discharge of water therefrom. A threaded thimble 30 is mounted on and communicates with an; )erture in the segment 23 and a. cap 31 is at apted to be screwed on said thimble to close said aperture. A handle 32 is mounted on thesegment 23 and spans the apex thereof. A pet-cock is mounted on and communicates with au aperture iu the bottom ofthe gutter 13.

In ractical use the food to becooked is placed) inv any desired vessel or receptacle which is then located in the vessel 10. later is `supplied to-the vessel 10 to the desired level which is indicated as below the top of either vessel 18, 19, 20. 'lhen the. valve 29'is closed and water issupplied to the dome orcovcr through the thimble 3() to a depth not overtlowin r the tine 16. .'lhen the. thimhlc is elosedby the cap 31 and the cover is placed in position as shown in Fig. l. 'lhen the vessel 1t), with its contents and cover, is placed over a burner and the gutter 13 is supplied with water to serve as a seal for the lower margin of the spherical segment 23. Steam is generated by boiling of the water in the vessel l() and serves tocook the contents ol the containing receptcles therein. ',llie water in the dome or cove'r also is heated and radiates downwardly in aid of the cooking process. Additional water may be discharged 'romv'the ceases dome or cover to the interior of the cooking vessel by opening the valve lVater condensed on the lower surface of the spherical segment 22 will be discharged from the margin thereof within the vessel 10. Any superfiuous water contained in and overflowing from the gutter 18 will be discharged within the vessel 10 over the upper margin of the wall thereof. When it is desired to empty the contents o the boiler or vessel 10, by tilting or invertin said vessel, it is preferable to tirst empty t through the pet-cock 35. This device may be employed to advantage as a dough raiser by removing the culinary articles shown and the trivet, placing a dough pan in the vessel 10 and charging the dome or cover with warm water.

The water seal provided by the gutter 13 is effective in retaining steam and odors within the apparatus save and except such as may escape through the re nstering notches 25, 26 and to this extent sai notches serve as vents and safety ports for the ap paratus.

Iclaim as my invention-w l. A cooking apparatus, boiler, concentric with the upper margin of said boiler', a water dome mounted on said boiler, said water dome com rising superposed spherical segments scale together near their margins, the margin of one segment extending within the wall of the boiler, the marcomprising a 'gin of the outer segment extending outside the wall or.y the boiler and within the gutter, and means for supplying water to said dome.

- 2. A cooking apparatus, comprising a boiler, a. gutter mounted on, outside of and concentric with the upper margin of said boiler, a water dome mounted on said boiler,

said water dome comprising superposed spherical segments sealed together near their margins, the mar in of one segment extending within the wzlof the boiler, the margin of the other segment extending outside the wall of the boiler, and within the gutter, means `for supplying water to. said dome, and valve controlled means for discharging water from said dome to said vessel.
